You should build an addIn, build the control containing the coordinates of the mouse, put it in a floating window (i attach you a transparent version one), and then configure the window position.
I think it was explain a while ago in this forum, I take my solution from here I think. Mmm I really don't remember, It was a year ago I build it. Anyway hope it helps.
Here is a picture of how it looks.

The code is just for the window, you need to implement the addIn.
I modified a bit mine and attach it, try it and see if that's what you need. I label in the screen X,Y because I do not know you map reference, I can not attach the hole code project because is like 8 mb, I put the addIn code and the Tool.xml. If you want build a project with the same name (CoordJamal), and replace the folder and then replace thr Tool.xml file in ..\Visual Studio 2010\Projects\CoordJamal\CoordJamal\CoordJamal\Config. Then you can change it as you want.
You can change the position of the X,Y window in the configuration when you add it in the viewer or in the Tool.xml, I use
<WindowPosition>
<HorizontalAlignment>Center</HorizontalAlignment>
<VerticalAlignment>Bottom</VerticalAlignment>
<HorizontalOffset>0</HorizontalOffset>
<VerticalOffset>0</VerticalOffset>
</WindowPosition>
Hope it help, let me know if it work or need something else.

Glad that it helps you.
I have not implemented a scale tool, they did not ask for it in my work. Sorry I can not help you there, If I start it I will let you know.
